Test Project

## Description

In XCode, the image set editor allows you to slice up an image (PNG's only) to be a 9-patch. In XCode IB, you can then reference that image set as the background for e.g. a UIButton and IB will render the image as a 9-patch based on the slicing done in the Image Set editor. If you then move that Image set to VS (or XS) and reference it as the background image for a button, iOS Designer will not render image at all but show a placeholder image (in VS, in XS the unsliced image is rendered). But on deploy to simulator or device, the image will be rendered as a 9-patch. 

## Steps to reproduce.

1. Open the attached test project in Visual Studio.

2. Open the Main.storyboard file in iOS Designer.

Expected result: Button will show sliced up image of Einstein.

Actual result: Only an image placeholder is shown

## Notes

Clean solution and deploy app to simulator to see how the image should have been rendered on the Design surface.

It appears fixed in great job, this one was a major pain in the ass. But another annoying one appeared: https://bugzilla.xamarin.com/show_bug.cgi?id=44818

Thanks so much for taking the time to submit this report! I attempted to reproduce this issue based on the bug description with the latest Visual Studio 2017 Preview version 15.3, and I was unable to hit the problem. If this issue is still occurring for you, please reopen this report and attach a reproduction, ideally starting with a new template project and then adding just the code necessary to demonstrate the issue.
